SHOE-SHAPING IvIACI-IINE.

Application filed December 12, 1913.

. State of Massachusetts, have invented certain Improvements in Shoe-Shaping Machines, of which the following description, in connection with the accompany drawings is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the manufacture of shoes, and has particular reference to the shaping of turn shoes after the lasting, sew- 7 111g, shoe turning and relasting operations have been performed. These operations leave the upper and the sole in a more or less distorted and rough-condition, and considerable smoothing and beating out are required in order to conform the shoe accurately to the shape of the last and to impart to the upper and the sole asmooth and finished appearance. Although machines have been devised for beating out the sole, the shaping operations above referred to upon turn shoes have been performed heretofore very largely by the use of hand tools.

An object of the present invention is to provide an improved machine embodying mechanical devices suitable for operating upon such shoes to conform them to the shape of the last and give them the required finished appearance.

T o the above end a feature of the invention consists in novel and improved beating mechanism comprising a shoe beating tool, herein shown as a lever having a portion formed for engagement with a shoe, and operating means comprising preferably a rotary cam arranged for sliding engagement with the tool to impart positive operative movement thereto without undue force of percussion and with reference to which the tool is in an inoperative position except when moved by pressure of a shoe into position to receive its operative movement.

The invention also provides a novel and convenient arrangement whereby a shoe beating lever is formed at one side of its fulcrum for engagement with a shoe and is moved by pressure of the shoe into position to receive operative movement from means engaging the lever at the other side of its fulcrum, and this arrangement constitutes another feature of the invention.

Specification of Letters Patent.

Serial No. 806,325.

A. further feature of the invention conslsts in a shoe beating tool suitably operated to impart a series of beating impulses and formed 1n one portion for beating the shank of a shoe sole and in another portion for beating a different part of the shoe such as the upper adjacent to the rand crease. This arrangement preferably includes also means whereby the force of the beating impulses may be varied, since a longer or heavier stroke of the beater is desirable for shaping the shank of a shoe sole than for smoothing the upper. 1

As a further feature the invention provides an improved shank beating I device comprising a novel combination and arrangement of beating tool and shoe positionmg means. The construction shown includes a pivoted shoe beating tool normally disposed in inoperative relation to its operating means and movable by pressure of a shoe against it into position to be operated by said means, together with shoe positioning means arranged to engage the shank of the shoe to assist the operator in guiding the shoe for effective treatment by the tool and to prevent the tool from being forced into position to engage its operating means continuously, thus insuring a more positive beating effect. Conveniently also the tool may be formed for beating the shoe upper by extending it beyond the shoe supporting means and providing an upper beating face on its outer end portion. I Still another feature consists in mechanism constructed and arranged for ready manipulation to vary the beating effect of a shoe beating tool, comprising preferably and as herein shown a pivoted stop arranged to limit the movement of the tool toward its operating means and movable quickly to a position to secure a different range of movement of the tool. Such a device is particularly useful in connection with a combined shank and upper beating tool, such as above described, since it is desirable, where both operations are to be performed in succession upon the same shoe, to change the adjustment of the beater very quickly.

These and other features of the invention, including certain details of construction and combinations of parts, will now be described more fully with reference to the accompanying drawings and pointed out in the claims.

In the drawings, Figure 1 is a view in Patented Mar. 14, 1916;

front elevation of the upper portion of a machine embodying a preferred form of the invention, Fig. 2 is anend view of the upper shaping device shown at the right ofFig. l, with the casing in section, Fig. 3 1s an end view of an alternative form of beating device, embodying means for shaping the shank of a shoe and the sides of the shoe upper, and Fig. 4 is a section on the line 4-4 of Fig. 3.

The machine comprises a head or frame 2 supported on a standard 4 at an elevation convenient for the operator in presenting a shoe to the shaping devices. The frame has bearings for a main shaft 6 which is driven from a belt 8.

One of the shoe shaping devices in the illustrated machine comprises a drum 10 which rotates with the shaft 6 and has at its periphery several rows of shoe beating rings 14, and above the drum a beater 28 arranged. to operate upon the side of the shoe simultaneously with the operation of the rings 14 upon the sole, this beater being operated by means of a shaft 16 driven by a belt 18. This device is not claimed herein, but in my copending application, Serial No. 597,190, filed December 14, 1910; and is herein shown to illustrate the type of machine of which the mechanism of this invention may conveniently form a part.

Near one end. of the main shaft 6 are formed a series of cams 36 and pivoted on the frame 2 at 38 is a beater in the form of a lever 40, the rear or lower end of which is adjacent to the cams 36 and. the upper end portion of which is provided with a concave shoe engaging face 42. The lever 40 is held normally out of operative rela.- tion to the cams 36 by a spring plunger 44, an adjustable stop 46 serving to limit movement of the lower end of the lever away from the cams. rendered operative by pressure of the work against the face42. An adjustable stop 48 limits movement of the lever toward its cam engaging position and thus determines the amplitude of its oscillations or shoe beating movements. The beating face 42 is shaped to extend deeply into the crease between the upper and the sole for beating out and smoothing any wrinkled or uneven portion of the upper not readily reached by other beating tools.

In Fig. 3 is shown an alternative form of beating device which combines substan tially the principal features of the device shown in Fig. 2 with means for beating the shank portion of the sole of the shoe. In this arrangement the shaft 6 is formed preferably with a single cam'projection 50, and the beating tool or lever, which is pivoted at 52 to the frame, includes a straight shank engaging portion 54 and an upper beater 56 at the end of the tool. The beater 56 is The beater is thus intended to perform substantially the same work on the shoe as the beater shown in Fig. 2, and its shoe engaging face may be shaped similarly tothe face 42. The shank beater 54has cooperating therewith rigid supporting means against which the shoe may be pressed and. guided during the shank beating operation, such means comprising in the construction shown a pair of parallel supports 58 on opposite sides of the tool. This supporting or positioning means prevents the shoe from forcing the tool to the limit of backward movement determined by the operating means and thus insures :amore positive beating effect. Theshoe beating lever has an arm 60 extending over the cam portion of the shaft 6 and normally held out of the path of the cam through the operation of the spring plunger 62, which positions the tool with its beating face projecting forwardly from the plane of the supports 58. Either portion of the heater is thus rendered operative through the pressure of the work against the respective shoe engaging face.

The means for limiting movement of the form of beater shown in Fig. 3 toward its operative position with reference to the cam 50 preferably comprises a stop member 64 which is pivotally mounted on the frame and has a shoulder 66 for engaging the rear face of the lever to limit the movement of the latter when the beating portion 56 there of is in use. When this stop is turned into the dotted line position the shoulder 66 is withdrawn from the path of the lever so that the latter may be moved farther backwardly and the arm 60 swung into closer relation to its operating cam. This position corresponds to the shank beating operation of the tool where wider oscillations of the beater are desirable. For retaining the stop securely in either of its positions of adjustment there is provided a spring plunger 68 which is shaped to enter notches formed in the curved portion of the stop. For securing a further adjustment of the i stop the latter is mounted upon anieccentric stud 70 which is adjustable by means of its slotted head to vary the position of the shoulder 66 when the stop is in its full line position shown in Fig. 3. For limiting the forward throw of the tool a stop 7 2 is provided, this stop comprising preferably a yielding spring-held plunger, as shown, so as to avoid possible injury or breakage of the arm 60.

In the use of the device shown in Fig. 3 the shank may be beaten by placing the shoe in the dotted line position and pressing the beating tool back into operative relation to the cam, the supports 58 serving to guide and position the shoe as it is pressed backwardly and moved to present different portions of the shank to the beater. Duringnus-,ara

this operation the stop is thrown into thebeing turned to present the shoulder 66 to the rear face of the beater so as to restrict the amplitude of its oscillations while performing the lighter work upon the upper portion of the shoe. With the use of this device it will be clear that the beater may be adjusted instantly by the operator to beat either the upper or the bottom of the shoe so that these different portions of the shoe may, if desired, be presented alternately to the respective operative portions of the tool to perform the two different operations thereon.

It will be apparent that the arrangement shown and described of a pivoted beater with one arm extending rearwardly over its operating cam and its other arm forwardly inclined for engagement with a shoe permits the shoe to be presented conveniently in position for treatment without interference by the operating means or other portions of the machine. I
